Can I use an UltraSync ONE with a Sound Devices MixPre-3?

Yes - The MixPre-3 will accept an external timecode source through the Aux IN jack of the device. All you'll need is one of our TCB-52 UltraSync ONE to 3.5mm jack cables, available from our online shop.

You can view more information about connecting to devices which don't have a dedicated timecode input here.
